 note = {application/pdf, The plant quarantine measures for tulip and lily bulbs were abolished in 1988. A removal of the quarantine made Japanese bulb growers face international competition in the markets. Since then the imports of bulbs, mainly from Holland, increased rapidly and bulb prices tended to decline gradually, while the Japanese production of bulbs did not decrease. The imports also introduced new varieties of bulbs to Japan. The demand for tulip bulbs increased greatly until the late 1990s, but in the 2000s the Japanese bulb markets stagnated. Bulb prices decreased, and the domestic production of bulbs decreased sharply, which caused a great reduction in the number of bulb farmers. Consequently, the rate of self-sufficiency for producing tulip bulbs in Japan decreased from 80% in 1988 to 20 % in 2006, even though the volume of imported bulbs decreased in the 2000s. This paper analyzes the demand and supply conditions of tulip bulbs, and reports estimates of the Japanese demand and supply functions of tulip bulbs by regression analysis. Demand depends upon the real price (in terms of consumption goods) of tulip bulbs negatively and the real national income positively, and shows that the demand curve shifted forward until 2001, and then shifted backwards. Domestic supply depends upon the prices of tulip bulbs and the rice prices positively., Working Paper},
